Dr. Michael Greller has been caring for my child, and I could not be more grateful for the level of attention and professionalism he provides. He takes the time to explain my child’s condition and treatment options in a way that I can fully understand, and he is always patient with our questions.

I have had problems with my knee for 30 years. I had Knee surgery in the 90s and it’s been gradually getting worse. I had gel injections and steroid injections for years. I went to see Dr. Greller for a 3rd opinion. I was so impressed with his bed side manner, his ability to explain what my problem was and explain all my options, that I literally left that appointment with a surgery date. At my prep appointment, he made sure I left there with EVERYTHING i would need the day I came home from surgery. He is the most efficient surgeon I have experienced. And I have had over 20 surgeries! Today is has been 3 months since I had surgery. My knee is doing great! I was officially discharged unless I need to go back. I absolutely recommend him!

I have been a patient of Dr. Greller for the past 24 years, and there is a reason I have stayed with him for so long. He is incredibly understanding, thoughtful, and caring. He truly listens and takes the time to understand what is happening in your life, not just your symptoms. His ability to connect, show compassion, and provide sound guidance has made all the difference in my care. I am truly grateful for the exceptional support and dedication he has shown throughout the years.
